Aligera AG561 - Compact E1 SIP Gateway
The AG561 is a compact, low-power E1 SIP Gateway, requires no forced ventilation, works quietly, is reliable and durable. With a minimalist WEB configuration interface, the most relevant information is easy to configure. The most complex configurations are accessible through a very flexible and intuitive command line interface (CLI).
AG561 supports up to 30 voice channels, translates signaling between the TDM and SIP network, performs media conversion and transcoding with support for multiple codecs, and has advanced echo cancellation capability on all channels simultaneously and support services fax on T. 38.
